"didn't notice a problem" is woefully insufficient here.

how carefully was this measured?  how was it measured?  across what
diversity of traffic.  what was the threshold for "a problem" here.

different use cases have different tolerances for the kinds of bad user
experience that google is concerned about here, both in terms of percentage
and in amount of impact.

please note that google has been super aggressively implementing and
promoting IPv6 for years, so implications that this is somehow related to
Google dragging their feet are silly.
